Martin commenced his musical career in 1979, joining UK band The Enid on bass guitar and keyboards a few months after completing a BA Hons degree in music. His most notable contribution to the band's catalogue was "Once She Was", an arrangement of the folk song melody "Scarborough Fair". He remained a member until 1981, citing his increasing dissatisfaction with the whimsical vocally-based direction that the band was taking as his reason for leaving. With fellow ex-Enid keyboard player William Gilmour he formed the instrumental rock band Craft, who recorded an album which was released in 1984. He subsequently focused on studio building and sound engineering for the rest of the 1980s, notably at Utopia and Swanyard Studios before designing and building his own studio in North London, England in 1991.
Sonic Innovation opened in 1992 and has been the headquarters for the majority of Martin's music production, recording, cd mastering and film music composition activities ever since.
